Working through first builder’s rudder rigging. The rudder pedals seem to have been mounted too far aft (5” behind centerline of firewall station). With this condition it’s impossible to depress the brake pedal with the rudder pedal at its forward-most travel. Unbolting the pedal assembly and clamping it as far forward on the support plates as possible seems to correct the geometry and result in good brake behavior.

Started riveting up the wing skin on my left wing. Think I've got the A/P roll servo figured out on the right wing. Using a base plate from Virgil to prototype in the Patrol along with a Dynon servo wing mount for an RV-6. The servo is the Dynon SV-42 with the extra long control arm which allows for 4.4" of total linear travel according to the spec sheet. Moved the base plate toward the forward wing spar to allow clearance of the control arm to clear the support frame tube of the aileron drive assembly. Base plate required notching on one side to clear wing stiffener.

Here is the A/P roll servo mounted in our wing. Similar idea using a plate riveted to the ribs. The pushrod is bolted just below the aileron pushrod. Checking the aileron travel throws at the bellcrank shows only 1" cable each way from center required for full deflection.

Slow going, but making progress on closing up the left wing. Was thinking I could squeeze all the wing to pocket skin rivets, but can only squeeze the top skin to pocket skin due to curvature of the pocket skins. The bottom wing skin had to be bucked. Hope I never have to drill out any of the CCP42 rivets called out in the wing manual for the pocket skin to rib fasteners. Also got my pitot mount mostly riveted in. Have two problem rivets that seem to defy proper setting...not sure what's going on. Will reassess another day when fresh.
